Be it known that I,- GIUsnPPE TAGLMBUE, of New York, in the county of New York and State of New York, have invented an Iinprovedv Apparatus for Testing Coal-Oil. l y The following fis a description of my appa' ratus, with drawings annexed, and lettered4 from A to R.

Referring vto the drawings, Figure 1 is a front'viewof my apparatus ready for trying the igniting of the gas from coal-oils., Fig. -2 1s a rear view with the cover open for trying the igniting of the oil. Fig.- 3 is a sectional 'View of the whole instrument. Fig'. 4g is aV 1 sectional'view of the base at E 1 11. 'ling'. 5

The views between Figs. ,1 and 2, and; be-

tween Figs'. 2 and 3 areV drawings of thecup,`

hereinafter des'cibed.l

The wholeinstrumentis constructed of `brass or any suitable material, with' the exception of the thermometer, which is of `course a glass tube. ff Y Ads a hollow stand resting o n the base E, with openings N N for the purpose of placing 1 therein a lamp, and some small openings, M

M2 M3, near the top to let out gases produced by fthe burning of the. lamp,

B is a vessel for holding water-and, if need be, coal-oil and waterattached to the stand A, extending above the stand and down into the stand, with a space between 'it and theY stand to allow the heat of the lamp to circulate around the vessel B.

Gis a cover for the vessel B. D is a tube attached to the covgr C, vextending above and below the coverv C, with r an' opening in theside above the cover C to display the thermometer-scale H, the glass tube of the thermometer extending through the cover and within the perforated tube D into the cup P.

F is a dome or cap covering an aperture in the cover C, vwith an opening, L, in front and an opening K, inthe top. The front opening,L,is for inserting a fiame of paper or wood, and the opening K is for the escape of the gases produced by the combustion, so as not to put out the Ham f' O O are openings in theleover C for the admission of air when needed, the air being excluded by the rotating coversJ J when necessary. 4

P is a cup for holding the coal-oil when testing its inflainmability and also the temper- -ature at which the gas explodes. Within the cup P is a ring, Q, into which the tube D of fthe thermometer is inserted. The ringQ is elastic, so as to adhere to the tube D, so that the vcup P may be lifted 4out of the vessel B.

The cup P is smaller than the vessel B; but there are-projections on the side of the cup P, which keep the cup P steady in the vessel B,-but allow 4thejwater which may be in the vessel B to flow upa'nd around thev cup P. There are lhole'siii the vessel B, near the top, to let any .excess'oi water flow out of the vessel B, and

not to allow any of it to run into the cupP. The ring Q is also to allow the coverG to be placed otherwise than over the vessel B, and at the same time hold it s'teadyin any desired position. The cup P isfor vtesting a small quantity of coal-oil. If it is desirable Y to test a larger quantity 'than the cup P holds, the vessel B may be filled one-third full of water, and then filled with oil on top of the water. In this case the cover C may be held in the position shwn'in Fig. 2-by a' sma1l spring, R, Fig. 2. The spring, coming outside the vessel B, presses the perforated tube D against the inside of the vessel B, and hold-- ing the cover G and its appendages in the position shown in Fig. 2.

The manner of using the instrument is as follows: Water is put in the vessel B and a lighted lamp under the vessel B in the opening N of the stand A. The coal-oil to be tested is put in the cup P, and placed in the vessel B, and covered by the cover C,.`with theopenings O O open. When the temperature of the oil is 100 Fahrenheit, a lighted paper is held in the opening L of the dome F, andwhen the vapor ignites the temperature is to be noted. To try the temperature at which the oil ignites, the cover is placed on one side of' the vessel B, leaving'the vessel B partly uncovered, as shown in Fig. 2, so that the lighted paper may touch the oil. Ifafter testing a sample or two of oil, the cover G should become heated, so as to interfere with any further trials, the cover G and its appendages may cover C and ts ppendagesur-i-x; ilrfrgf 5;; Witnesses: sition other than over the vessel B.
